Subsystem Equipment. Subsystem equipment connects directly to the System or enhances the System functionality. These subsystems include dispatch consoles, CEBs, Key Management Facilities (KMFs), Network Management Terminals (NMTs), telephone interconnect systems, logging recorders, data servers and BDAs that apply to a specific building.

2..1 Console System Console systems are made up of a single operator position or multiple operator positions as a console site. The site may utilize T1 or a network connection to the zone controller. The bandwidth requirements are provided by the manufacturer. The ALMR system is a closed network, requiring all connectivity to be approved by the System Manager and Information Systems Security Manager (ISSM).
2.1.1 Consoles may operate using control stations to access the system. Consoles using this configuration utilize an RF connection for the talkpaths and have no network requirements. The radios are required to be on the ALMR approved subscriber list.
2.1.2 The conventional channel gateway (CCGW) enables both analog and digital channels to interface with consoles with no need for a separate hardware network and channel banks. This capability provides system interoperability with conventional radio systems through a patch, or by communicating directly with non-system radios.
2.1.3 Tie trunks are connections between CCGW ports and disparate systems. These can be permanent or temporary patches that link different dispatch systems and their associated resources.
Subsystem Equipment. Subsystem equipment connects directly to the system equipment or enhances the System functionality. These subsystems can include dispatch consoles (MCC7500e and MCC7500), Key Management Facilities (KMFs), Network Management Terminals (NMTs), telephone interconnect systems, logging recorders, data servers and bi- directional amplifiers (BDAs).
2.2.1 Console System Agencies with dispatch consoles are operating the current MCC7500e or MCC7500 models.
2.2.2 Key Management Facility The Motorola™ ASTRO 25® system allows two-way radio transmissions to be encrypted and secure. The Key Management Facility (KMF) is a solution for centralized key management and over-the-air-rekeying (OTAR). The KMF equipment includes a KMF application server, KMF database server and KMF client.
